概括
静脉收缩宽度 (VCW) 是慢性大动脉反 (AR) 的最可复制的心声测量方法. 心脏磁共振 (CMR) 提供了卓越的可重现性,并且在AR评估不清楚时,应补充胸前回声心电图 (TTE).
科学领域:
- 心脏病学 心脏病学
- 医疗成像医学成像
- 诊断工具 诊断工具
背景情况:
- 使用心声回声仪对慢性大动脉反 (AR) 的准确评估,由于观察者间的变异性,存在挑战.
- 在临床实践中,指南推的心声回声学参数需要对其可重现性进行评估.
研究的目的:
- 评估指南推的慢性AR心声学参数在现实环境中的可重现性.
- 评估心脏磁共振 (CMR) 作为AR评估的补充成像方式.
主要方法:
- 99名AR患者的回顾性分析,通过胸回声心脏成像 (TTE) 评估.
- 一组22名患者也接受了CMR.
- 通过使用压力半衰期 (PHT),静脉收缩宽度 (VCW) 和吐孔面积 (EROA) 等参数对AR严重程度进行分级,通过科恩的卡帕和布兰德-阿尔特曼分析评估观察者之间的一致性.
主要成果:
- VCW显示出最高的可复制性 (总体 κ=0.77) 和可行性 (68.7%).
- PHT显示了观察者间不良的一致性 (总的 κ=0.36),具有显著的可变性.
- EROA的同意程度中等 (总的 κ=0.55),但可行性低 (30.3%).
- CMR参数表现出极好的可重现性,独立于读者专业知识.
结论:
- VCW是AR评估中最可靠的心声回声参数.
- PHT和EROA分别受到可变性和可行性的限制.
- 在慢性AR治疗中,CMR提供了卓越的可重复性,并且应在不确定的TTE发现的情况下早期考虑使用.

Aortic Regurgitation II: Clinical Features and Diagnostic Tests
361
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Aortic Regurgitation I: Introduction
423
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Aortic Regurgitation III: Medical Management
359
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Mitral Regurgitation II: Clinical Features and Diagnostic Tests
313
Mitral regurgitation (MR) is a valvular heart disorder in which the mitral valve fails to close tightly, allowing blood to leak backward into the heart. Understanding the clinical manifestations, assessment, diagnostic findings, and medical management of MR is crucial to effectively managing affected patients.Clinical Manifestations of Mitral RegurgitationMitral regurgitation can be acute or chronic, each presenting differently and requiring different approaches:1. Acute Mitral...

Aortic Regurgitation IV: Nursing Management
252
A nurse managing a patient with aortic regurgitation begins with a comprehensive assessment, including a review of the patient's medical history, family history, and lifestyle factors. During the cardiac examination, the nurse listens for heart sounds and checks for signs of valve abnormalities. The nurse also observes for symptoms such as dyspnea, orthopnea, and paroxysmal nocturnal dyspnea and assesses the patient's endurance and daily activity tolerance.Based on the findings, the nurse...
